Interviewed for a role in the Dublin office with the hiring manager where he described the role and asked me a number of broad questions without digging too deep. Interview was more conversational in nature but he covered a lot and probed if I didn't give enough info to answer the question fully. Then a number of interviews with people who delved more into technical knowledge, digging a bit deeper. Questions were tough but I wouldn't say they were out of order or anything. Any time I went down the wrong track they gave me a nudge that maybe I should reconsider my answer in the context of the question and they wrote down everything I said, so I got the feeling as long as I could talk about the area in question it might be a good idea if I didn't know the specific answer. Just posting because I read some horror stories on here that made me anxious before I did the interview. I'd say just make sure you prepare the standard technical questions you'd expect, and make sure to know your cv and have it fresh in your mind so you can draw on your past experiences to give examples and you'll be fine.
